Great neighborhood, quiet building, with a great pool. I stay for 6 weeks and pretty much had all my needs met. The Ceil is a large and busy condo development, but you don't really notice everyone else. This part of Ekkamai is somewhat non-descript, but it's easy enough to cross over to Thonglor or catch a motorcycle taxi to Sukhumveit.
The apartment itself is a nicely design small minimalist flat all greys and blacks and whites with lower end although still very functional fixtures and appliances. Great view, and lots of light overall. It was only average in terms of preparing food at home, with limited supply of kitchen utensils and cutlery but most people will probably eat out anyway -- and there are plenty of options for that. Walk to Ekkamai BTW is probably 15-20 minutes for most people - just a bit longer than is preferred but still convenient.
Although it was fortunately addressed within a few hours, upon arrival I discovered that the water service had been turned off a day to before, leaving me unable to shower, use the toilet or draw water from the tap. Ratthapol was mortified and rushed over to the flat as soon as he received my message, but after a long flight I wasn't happy about the mix up.
The gym was too small for my taste, but I did use it quite a bit. The pool is fantastic. Parking is easy for those who have a scooter.
Other than that - everything was positive and Ratthapol was very responsive.
